Question 8

True/False

The fit of the regression equations The fit of the regression equations = b<sub>0</sub> + b<sub>1</sub>x + b<sub>2</sub>x<sup>2</sup> and = b<sub>0</sub> + b<sub>1</sub>x + b<sub>2</sub>x<sup>2</sup> + b<sub>3</sub>x<sup>3 </sup>can be compared using the coefficient of determination R<sup>2</sup>. = b0 + b1x + b2x2 and The fit of the regression equations = b<sub>0</sub> + b<sub>1</sub>x + b<sub>2</sub>x<sup>2</sup> and = b<sub>0</sub> + b<sub>1</sub>x + b<sub>2</sub>x<sup>2</sup> + b<sub>3</sub>x<sup>3 </sup>can be compared using the coefficient of determination R<sup>2</sup>. = b0 + b1x + b2x2 + b3x3 can be compared using the coefficient of determination R2.
